From armed roots to airline routes in South America: A dual imprinting perspective
Strategic Management Journal, EarlyView.Abstract Reserch Summary We propose that founding partner relationships can leave distinct imprints on organizations that differ in durability and in how they respond to subsequent changes involving the founding partner. Examining South American airlines founded between 1919 and 1984, we argue and find that such relationships simultaneously create an ...

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices
Small, EarlyView.True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key

Small Methods, EarlyView.Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites
Safety Science and Technology, EarlyView.Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Assessing Capability Complexity Using Enterprise Architecture Framework
Systems Engineering, EarlyView.ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
Systems Engineering, EarlyView.ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to
